It might be because FCPX is down-scaling the 4k as an effect, which requires rendering the timeline for highest quality. If I render the timeline via CTRL+R, I don't see that.

However even with FCPX on Better Quality it looks like there's a little fuzziness if playing back an unrendered 1080p timeline. This is similar to how Premiere 2019 looks if I set the playback quality to 1/4 or 1/4 instead of full quality. In FCPX I only see significant blur if your playback is set to Better Performance instead of Better Quality (under the Viewer upper-right drop-down menu). Has anyone found a solution to this issue yet? The only workaround I've found is to encode the footage to 1080p through Compressor and then import them to FCPX but this is really time-consuming and it makes no sense, to be honest. So this issue is specific to Final Cut X (latest version). The image might not be as sharp as in 4k but it's definitely not blurry. Importing the same footage on a Premiere Pro 1080p timeline (I installed the demo just to check) or Screenflow does not give me a blurry image. Now, all the responses I've found is that you're throwing away resolution when you downscale etc. I am NOT working with proxies and exporting the footage yields the same blurry results. THen the footage becomes blurry to the point that the characters have lost all their sharpness. When I import the footage in FCPX they play fine until I drop them in the timeline. I've recorded some 4K screen captures but I want to edit them on a 1080p timeline in FCPX. This topic has been discussed a while ago but I never found a resolution that's why I decided to open a new thread.
